Question
i need the answer quickly
A sample of blood of density 1060 kg/m^3
is flowing at a velocity of 0.2 m/s through a
blood vessel of radius r = 0.004 m and
length L = 1 cm. If the flow resistance is
R_flow = 8.1 x 10^5 Pa.s/m^3 then the
viscosity of this blood would be equal to:
4.07 x 10^-3 Pa.s
4.07 x 10^-2 Pa.s
8.14 x 10^-2 Pa.s
8.14 x 10^-3 Pa.s
Assume the radius of the aorta is 1.1 cm,
and the average speed of blood passing
through it is v_a=0.5 m/s. If a typical
capillary has a radius of 4 x 10^-6 m, and
there are 6 x 10^9 capillaries, then
calculate the average speed of blood flow
in the capillaries.
Ov_c= 1.2 x 10^-2 m/s
v_c = 6.3 x 10^-4 m/s
v_c= 8.8 x 10^-4 m/s
v_c = 3.9 x 10^-2 m/s
